# (Centered squares) dipyramidal numbers

From OeisWiki

Although the (centered squares) pyramidal numbers **ARE NOT GLOBALLY CENTERED** (only the original squares are), the (centered squares) dipyramidal numbers turn out to be **GLOBALLY CENTERED** (putting 2 square pyramids back to back creates an octahedron, which has global symmetry) and they are the centered octahedral numbers, which are **GLOBALLY CENTERED**.
